Mustajärvi | EMX Royalty Corp.

EMX acquired a 1% Net Smelter Returns (“NSR”) royalty on the Mustajärvi Project in Finland from Aurora Exploration Oy, a private Finnish company (see EMX news release dated January 30, 2024). The Mustajärvi project is located in Northen Finland in the Central Lapland Greenstone Belt and is hosted within the Mustajärvi shear-zone (MSZ). The MSZ lies between the regional Venejoki and Sirkka shear zones, which host numerous gold occurrences and deposits including Rupert Resources’ recent Ikkari gold discovery.

Gold mineralization at Mustajärvi appears to be developed within “dilational jogs” along the MSZ. Drill defined zones of mineralization have now been reported over a 2.1km trend. The mineralization chiefly occurs as quartz-carbonate-tourmaline veins along contacts between intercalated siliciclastic meta-sediments and mafic-ultramafic volcanic rocks, a common control of gold mineralization in the region. The currently defined zones of mineralization remain open along strike at both ends of the trend as well as at depth.

Recent exploration activities concentrated on the “East Target”, where Firefox reported the discovery of a new zone of gold mineralization in 2022-2023. Drill intercepts in the East Target include hole 22MJ006 with 13.85 meters of 28.74 g/t Au from an in-hole depth of 24.15 meters, 22MJ021 with 15.5 meters of 13.09g/t Au from an in-hole depth of 11 meters and hole 23MJ004 with 20.45 meters of 5.14 g/t Au from an in-hole depth of 12 meters¹. Elsewhere on the property, significant intercepts include drill hole 21MJ010 with 16.45 meters at 7.69 g/t Au from an in-hole depth of 154.15 meters¹. Firefox and previous explorers have drilled a combined total of 14,158 meters on the property so far.

*Nearby mines and deposits provide context for the project, but do not necessarily indicate similar size, styles or grade of mineralization within the project.

¹ In its news releases dated September 9, 2021, September 6, 2022, January 18, 2023 and July 18, 2023 Firefox has reported that “drilling is believed to be perpendicular to the dip of the mineralization, however true widths are not yet known and will be confirmed with additional drilling and geologic modelling.” Although these results were reported in compliance with NI43-101 protocols and are believed to be reliable and relevant, EMX has not performed sufficient work to verify the published assay results.
